WEB FABRIC

Abstract

A web fabric includes a plurality of first threads and a plurality of second threads. Each of the first threads is made of at least one TPU (Thermoplastic polyurethane) filament. The first threads are arranged at intervals. The second threads are arranged at intervals and ties around respective one of the first threads so that the web fabric is formed with a plurality of through holes. Each of the second threads is knotted with the first threads to form a plurality of first knots. Each of the second threads is knotted itself between any two adjacent ones of the first threads to form at least one second knot. The first threads are separated apart by the at least one second knot to prevent the first threads from touching each other.

Claims

1. A web fabric, including a plurality of first threads and a plurality of second threads, each said first thread being made of at least one TPU (Thermoplastic polyurethane) filament, the first threads being arranged at intervals, the second threads being arranged at intervals and tying around respective one of the first threads so that the web fabric is formed with a plurality of through holes, each of the second threads being knotted with the first threads to form a plurality of first knots, each of the second threads is knotted itself between any two adjacent ones of the first threads to form at least one second knot, the first threads being separated apart by the at least one second knot to prevent the first threads from touching each other; wherein each of the second threads has an outer diameter smaller than one fifth an outer diameter of each of the first threads; wherein the first threads are integrally connected to be a thread extending back and forth, and each said first thread extends straightly through a plurality of said first knots.

2. The web fabric of claim 1, wherein each of the second threads is made of artificial sinew or TPU filament.

3. The web fabric of claim 1, wherein each of the first threads is compressed by the second threads at the first knots to have an outer diameter which is 0.9-1.0 time an original outer diameter of each of the first threads.

4. The web fabric of claim 1, wherein a distance between any two adjacent ones of the first threads is 1-5 times an outer diameter of each of the first threads, a distance between any two adjacent ones of the second threads is 2-5 times an outer diameter of each of the first threads.

5. The web fabric of claim 1, wherein each of the first threads is a part of a monofilament thread made up of a single filament extending back and forth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Please refer to FIG. 1 to FIG. 2, the web fabric of the present invention includes a plurality of first threads 10 and a plurality of second threads 20. Each said first thread 10 may be made of a single TPU (Thermoplastic polyurethane) filament which is integrally formed, or each said first thread 10 may be made up of a plurality of TPU filaments. The first threads 10 are arranged at intervals. The second threads 20 are arranged at intervals and ties around respective one of the first threads 10 for fixation so that the web fabric is formed with a plurality of through holes 30. Each of the second threads 20 is knotted with the first threads 10 to form a plurality of first knots 21. (The first thread and the second thread are not processed by heat for melting.) Each of the second threads 20 is knotted itself between any two adjacent ones of the first threads 10 to form at least one second knot 22. The first threads 10 are separated apart by the at least one second knot 22 to prevent the first threads 10 from touching each other. The first threads 10 are integrally connected to be a thread extending back and forth, and each said first thread 10 extends straightly through a plurality of said first knots 21.

[0016] In the present embodiment, each of the second threads 20 is made of artificial sinew, TPU filament, or other conventional filament for weaving. Preferably, each of the first threads 10 is a part of a monofilament thread made up of a single filament extending back and forth to be plural rows of first thread 10.

[0017] Besides, each of the second threads 20 has an outer diameter smaller than one fifth an outer diameter of each of the first threads 10. Each of the first threads 10 is compressed by the second threads 20 at the first knots 21 to have an outer diameter which is 0.9-1.0 time an original outer diameter of each of the first threads 10, as shown in FIG. 1A. On the other hand, a distance between any two adjacent ones of the first threads 10 is 1-5 times an outer diameter of each of the first threads 10, and a distance between any two adjacent ones of the second threads 20 is 2-5 times an outer diameter of each of the first threads 10.

[0018] The first threads and the second threads are fixed to each other by knotting instead of meting. Thus, the threads are fixed firmly, and the web fabric has a three-dimensional appearance. In addition, the first thread is made of TPU to be difficult to be compressed radially when knotting to provide a more three-dimensional appearance. The TPU first thread further has a higher friction to prevent from slipping. Besides, the TPU first thread has a better tolerance of extension, so the web fabric can be used in wide fields and is more durable. In addition, the TPU filament is better in wear resistance.
